8 Claims.

This invention relates to window glass guides of the type comprising a channel-shaped strip adapted to be applied to a window and bent to conform to the outline of the window opening therein to slidably support and cushion the edges of a window pane for movement to open and closed positions, one object of the invention being to provide an improved window channel, of the above variety having a more readily bendable but strong. and eihcient type of construction.

Another object is to supply such a window channel having a more light and flexible construction adapted to be bent to fit a curved window outline without puckering or otherwise distorting the cross-sectional shape of the channel.

A further object is to provide a window channel having the above advantages in a type of construction capable of being manufactured at relatively low cost and readily installed in its groove in the window frame ready to receive the window pane to be supported- To these and, other ends the invention resides in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features being point-ed out in the claims at the. end of the specification.

Fig. 5 is a sectional view on the line 5-5 in Fig. l.

The invention is disclosed in the present instance, in a preferred embodiment comprising generally an outer supporting frame and an inner lining therefor to slid-ably guide and cushion the window pane to be supported. Such frame, indicated generally at IE1, is preferably formed of a multiplicity of transversely extending strands of resiliently flexible material, such as wire, of the known variety capable of being bent to shape and of subsequently maintaining such shape with a substantial degree of resilience. These wire strands are preferably formed by a length of wire, which is bent alternately in opposite directions and carried back and forth, as shown in Fig. 3, to form a strip of the desired width for bending to make the frame, the wire strands ll thus formed being preferably laid in 2 closely spaced, parallel relation, with the adjacent strands connected by reversely bent loops l2 at the opposite edges of the strip, as shown. These wire strands are connected and further maintained in position in the plane of the strip by longitudinally extending elastic strands arranged along the edges of the strip as at I3 and also in longitudinally extending inner bands, in-

dicated generally at M and I5, positioned to lie.

in the side walls of the strip when bent into U-shape. A third band 16, positioned to lie along the bottom of the channel, is preferably composed of cotton strands loosely and yieldably interconnecting the wire strands, as hereinafter more fully described.

Such longitudinally extending connections between the wire strands are formed by strands of elastic material or yarn, using the term yarn in its broad sense as inclusive of either twisted filaments, or filaments of natural or synthetic rubber, or elastic plastics, such as elastic nylon, a variety of filaments being suitable for this purpose provided that they have substantial elasticity and durability. Such elastic filaments or strands may be either knitted through the wire strands, or braided through them, or interwoven therewith. Knitting of these elastic strands is at present shown and preferred because of the loose arrangement and extra length afforded by knitted loops enclosing the wires. Such elastic strands are here shown as separately knitted through the wires, but these strands may be also interlooped with each other and knitted together, if so desired.

The fiat strip so constructed is then bent over suitable forms along longitudinal lines intermediate the bands Hi, l5 andv It, respectively, to convert the strip to the substantial U-shape shown in Fig. 2 having a bottom portion [1 and side walls, l8 and I9, as shown. The bottom wall I1 is of ample width to space the side walls [8 and 19 from the side faces, as 20, of a window pane to be supported and the side walls l8 and. I 9 are preferably dished or curved inwardly, as shown, to increase their stiffness and also to facilitate the use of a liner having cushioning surfaces with plush or pile fibers of optimum cushioning length for contact with the window, as hereafter described. By varying such curvature of the side walls and the angle at which they extend from the base ll, the channel may be readily adapted for use with window panes of varying thickness. A more widely spaced relation of the side walls for a thicker window, for example, is indicated at l8a and l9a.

amass? The supporting frame, such as described above, is provided with a fabric lining strip, indicated generally at 2|, such as shown in Figs. 2, 4 and 5. This strip comprises longitudinal or warp strands 22 of one of the elastic varieties described above as employed in the supporting frame. With these warp fibers are interwoven weft or filler strands 23, of cotton or other suitable material, to form a base for the plush or pile cushioning bands 24, 25 and 26, the bands 24 and 26 being positioned to extend longitudinally of the side Wall between the top and bottom thereof, while the band 25 extends longitudinally of the bottom Wall 11. These cushioning bands are preferably formed by interweaving with the base fabric a series of longitudinal strands 21 (Fig. 5), of cotton or the like, and looped strands 28, of wool or other suitable material, the loops being cut to form the plush or pile surfaces 25, 25 and 26, as well understood in the art. The height of the pile is such as to afford optimum supporting and cushioning effect and the side walls l8 and 19 of the frame are suitably spaced for proper contact of the pile with the window. The liner fabric 2| is capable of being elastically stretched in a longitudinal direction because of the elastic nature of its warp strands and of the yieldable type of weaving employed in applying the pile surfaces and this liner is preferably cemented to the inner surfaces of the supporting frame by one of the known varieties of flexible and moistureproof cement. The outer edges of the strip are secured to the outer edges of the supporting frame in any known and suitable manner, preferably by a tubular bead 29 of non-corrosive metal, the edges of which are applied in clamping engagement with the frame and liner to secure them together and the head to both. Such a bead serves also to afford an attractive edge finishing for the channel.

It is apparent from the above description that the invention provides a channel of strong but readily bendable construction capable of being bent to conform to the curved outline of a window. In such bending, the bottom and side walls of both the supporting frame and liner together stretch and yield as may be necessary to conform to the radius of curvature or length of are employed and such elastic yielding enables the channel to maintain its cross-sectional dimensions and shape, thus eliminating the tendenci to buckle and pucker, as well as to reduce the depth of the channel shape, which has been commonly characteristic of prior constructions. At the same time the construction is of a light nature, economical of materials, and adapted to be manufactured and applied for use at relatively low expense.

It will thus be seen that the invention accomplishes its objects and while it has been herein disclosed by reference to the details of a preferred embodiment, it is to be understood that such disclosure is intended in an illustrative, rather than a limiting sense, as it is contemplated that various modifications in the construction and arrangement of the parts will readily occur to those skilled in the art, within the spirit of the invention and the scope of the appended claims.
